The built-in GPS navigator makes it possible to save on the purchase of navigation devices.

The easiest way to connect

Subwoofer in the car

In this case, we mean the use of an active subwoofer, which does not require an additional amplifier. Started:

• We select a position for the subwoofer and supply power to this location. It is best done directly from the battery. If this is not possible, then as a last resort you can connect it through the cigarette lighter.

Note. It is very important to check everything correctly and maintain polarity. It is also important to additionally install a capacitor to power the subwoofer, so that when peak loads arise when playing low frequencies, problems do not arise.

• The subwoofer is connected to the car radio using a “tulip” wire or screw power contacts;
• After the connection is made, the setup will be reduced to limiting the upper limit of the speaker's low frequencies and selecting the speaker's oscillation phase.

How to connect a subwoofer

Note. Typically, many subwoofers have this feature.

A problem when connecting a subwoofer can be poor matching of amplitude-frequency characteristics. If you choose a subwoofer that has a special function that makes it possible to adjust the upper limit frequency using adjustment, then this would be considered as an advantage.

Basic Connection Considerations

Before connecting, you need to disconnect the negative terminal of the battery.

The receiver should be installed away from heat sources, in a place where there is no direct sunlight, dust, dirt and large vibrations.

For connection, you should use special automotive cables and wires with the appropriate cross-section to avoid voltage drop.

The installation process involves the following steps:

1. Using special keys, you need to remove the radio from the installation frame.
2. Then the frame in which the device will be installed must be inserted into its regular place on the dashboard. The frame should be installed without any force to avoid damaging it. After installation, the frame must be secured.
3. At the next stage, you need to connect the antenna and connect all the wires and cables to the connectors according to the connection diagram, which is in the instructions for the Mystery radio.
4. Next, the device is inserted into the frame until it stops until the springs fit into the corresponding grooves.

To increase noise immunity, the car radio housing must be connected to a metal part of the body.

After installing the radio, the battery is connected. For some models, power from the cigarette lighter is sufficient, so they can be connected to it.

Setup Basics

The device is controlled and configured using buttons located on the front panel.

They have the following purpose:

• button for removing the muzzle (front panel);
• on/off;
• volume control;
• selection of operating mode;
• move to next track;
• removing the disc;
• selecting a radio station;
• buttons for turning on various playback modes;
• go to the previous track;
• selection of frequency range;
• instant sound on/off;
• system initialization (data reset).

The front panel has connectors for connecting external devices, SD memory cards, and USB.

Similar control buttons are located on the remote control that comes with the device. The purpose of the control buttons is described in detail in the car radio manual. It also describes how to correctly perform general settings, as well as set up the radio, sound, time and date, image, steering, etc.

Connection via amplifier

This assumes connecting a passive subwoofer. So, let's begin:

• The first thing you need to do is connect the power. First, we connect the negative wire to the amplifier to the GND terminal. Don't forget to connect the other end of the wire to the car body.

Note. If you do not use a set of wires, but only pieces, then remember the following rule: the negative wire should always be thicker than the positive one!

• It is recommended to pay special attention to the cable cross-section. There is no need to skimp on good nutrition;
• We further connect the positive wire to the amplifier at terminal +12. Be sure to install a fuse, preferably as close to the battery as possible. It will protect against short circuit or sudden fire;
• In those places where the wire comes into direct contact with the metal of the body, it must be protected without fail. So, corrugations and bushings, as well as electrical tape, will cope with this task perfectly.

Note. We remember that connecting to the battery occurs at the very last moment.

• We connect with the REMOTE terminal. On all modern cars, or rather, in its head unit system, there is a blue wire with a white stripe applied to it. When the head unit is turned on, 12 volts are supplied to the wire and the amplifier turns on. Accordingly, if you turn off the car radio, the amplifier will also turn off. Convenient and safe.

Note. If for some reason there is no such wire, then the REM terminal is already connected to the ACC circuit. This goal implies such a position of the key in the ignition switch when only the radio works (typical for foreign cars).

• We carry out RCA cables. They connect the sound of the car radio with the amplifier (see How to connect an amplifier and subwoofer to a car radio: you are your own master). We try to lay these wires as far as possible from other cables and other sources of interference.

Note. If there is excess cable left, then it does not need to be twisted into a ring, but it is recommended to lay it in a snake.

If the Mystery car radio has one pair of line outputs, and the connection is to a 4-channel amplifier, it is recommended to use the Y-connector. Although with this connection the fader is lost. If the amplifier has an INPUT-SELECTOR, then this is the same Y-connector. We connect the subwoofer and this operation can be considered complete.

Possible malfunctions and ways to eliminate them

Like any device, the radio may have malfunctions.

Connecting the Mystery subwoofer

Connect the mystery subwoofer to the radio

If you have a Mystery radio in your car, then there is a reason to connect a Mystery MBV-251A subwoofer to it. It is active and everything necessary for connection is included in its kit. Started:

• To begin with, it is better to check its operation at home. If the sound power is satisfactory, then everything is fine.

Note. It will also be useful to measure with a tester how much electricity this subwoofer consumes. As it turns out, when completely turned off, this subwoofer does not consume anything. When enabled, even if you turn off the bass, the speaker will consume power. Thus, it would be more appropriate to place the button on the control wire rather than on the thick positive wire.

• It's time to lay the wires. It is advisable to take the minus from the bolt securing the rear seat of the car and tighten it with a nut to ensure good contact.

Note. Laying a thick positive cable into the interior can be difficult. If you don’t want to drill the body, you can push it into the wiring harness going into the interior. In a word, decide for yourself - the easiest way is to make a hole with a drill and insert the wire.

• After the positive wire is inserted, you will need to connect it to the battery terminal (you can use a 10mm bolt);
• The remote bass control can be mounted directly above the fuse box. Here the regulator will not be conspicuous and the place is convenient, always at hand.

The installation should be carried out so that after turning on the head unit, use the button to turn on or off the subwoofer if it is not needed. Very comfortably.
